TechCrunch quotes figures from market tracker Comscore that show Twitter is enjoying exponential growth. In February, Twitter had 10 million unique.

Facebook still seems far ahead, with around 200 million unique (making it one of the web’s top 10 properties). But as TechCrunch points out, Twitters growth is still accerating. In March it added 9 million tweeters, in April 13 million.
